While I've been tinkering with the PDP 8/e I just
took out of storage,
I've found that a couple of the front panel bulbs are burned out.
I know that this has been discussed here before, but does anyone have
a clue where I can get replacements that will work?
Some people have had some luck with my page:

I understand that the bulbs are type T1, 14V @ 0.40A,
with .125 pin
spacing, and 0.75 tall. I have a DEC part number, but, of course, that
today is useless. I've searched around the net some, but can't find
anything like that.
I don't think that is the correct voltage for an 8/e bulb, though it is
about right for an 8/i bulb. I believe the 8/e uses 10V bulbs, though many
seem to have been rlamped with 8/i bulbs, for some reason. (Perhaps the
dimmer presentation was acceptable, and the higher voltage bulbs lasted
longer?)
I believe the original 8/e bulb was equivalent to the CM2309. Those are not
easy to find these days, but the CM7371 are readily available, and should
work OK (and have a longer lifespan, too).
(The 8/e lamps are already socketed, so you lucked out there.)
